问题 I am using Django's modelform and its really good. How can I highlight the actual text box (e.g. border:red ) if there is a validation error associated with it. Basically what i want is to add a class (error) if there is a validation error to a field. 回答1: What about defining error_css_class? http://docs.djangoproject.com/en/dev/ref/forms/api/#styling-required-or-erroneous-form-rows? class MyForm(ModelForm): error_css_class = 'error' 回答2: Expanding upon errx's answer. Add the CSS .error input

问题 I've been doing things like this in the clean method: if self.cleaned_data['type'].organized_by != self.cleaned_data['organized_by']: raise forms.ValidationError('The type and organization do not match.') if self.cleaned_data['start'] > self.cleaned_data['end']: raise forms.ValidationError('The start date cannot be later than the end date.') But then that means that the form can only raise one of these errors at a time. Is there a way for the form to raise both of these errors? EDIT #1 : Any

问题 I have a ChoiceField in a bound form, whose choices are: [('all', 'All users'), ('group', 'Selected groups'), ('none', 'None')] In the template, I have no problem accessing its bound value (the actual value to be stored; the first element of each tuple) and the choices. With these pieces of info in hands, I know I should be able to access the display values, or the second element of each tuple. But how can I do that in the template? Thanks. 回答1: I doubt that it can be done without custom

问题 I've got a model, with FileField . When I edit this model in a view, I want to change the "current" value of FileField which gets displayed in the view form. Let me explain. models.py: class DemoVar_model(models.Model): ... Welcome_sound=models.FileField(upload_to='files/%Y/%m/%d') forms.py: class DemoVar_addform(ModelForm): ... class Meta: model = DemoVar_model views.py: soundform = DemoVar_addform(instance=ivrobj) .... return render_to_response(template,{'soundform':soundform}, ....) Now I

问题 I'm certain I'm doing something really obviously stupid, but I've been trying to figure it out for a few hours now and nothing is jumping out at me. I'm using a ModelForm so I can expose a few fields from a model for editing. 2x ImageField, 1x TextField. The Form is processed and the TextField works. The two ImageFields do not work and they're why I'm here today. I'm using Django 1.0.2 Here's the relevant code (ask if you need more -- and I'm not including the HTML because that part appears
